[Neuro-autonomic mechanisms of the maintenance of blood oxygen balance in patients exposed to the effect of a gaseous hypoxic mixture].

The authors discuss the mechanisms of compensatory reactions of the human vegetative nervous system, its central and peripheral parts, in breathing a gaseous hypoxic mixture. Five types of neurovegetative reactions of the organism aimed at maintaining the oxygen balance in blood were distinguished. The interrelationship of values reflecting the activity of the central and peripheral parts of the vegetative nervous system in exposure to emergency effects is discussed.
